Instance Method Details

#lookup(key, default, scope, order_override = nil, resolution_type = :priority) ⇒ Object

Calls the backends to do the actual lookup.

The scope can be anything that responds to [], if you have input data like a Puppet Scope that does not you can wrap that data in a class that has a [] method that fetches the data from your source. See hiera-puppet for an example of this.

The order-override will insert as first in the hierarchy a data source of your choice.
